Update on my build. Found that my FPR had a steady leak from its diaphragm which explained my rich idle. Furthermore I decided to delete my traction control unit all together because I found post MAF leaks at the ASC throttle body. Beforehand I had also been throwing a TPS fault code after about 10-15 min of highway driving, even with a new TPS. The traction control delete has since prevented that TPS code from coming up again. Stalling cold start I dle issues have subsided! The only thing now is my confusion with the idle fuel maps, because once the car is warm I can't seem to lean out the idle AFRs from any changes from the idle fuel maps alone. The car currently runs at 10.9-11.1 AFR at idle....am I missing something?
